   In a population, the stochastic variable A follows a probability distribution with mean 77 and standard deviation 21. We draw from this population a sample of size n = 7. Then the sample mean follows a distribution with

   
   
   1. FALSE: Μ = 11 and σ = 3
   2. FALSE: Μ = 11 and σ = 7.94
   3. FALSE: Μ = 77 and σ = 3
   4. TRUE: Μ = 77 and σ = 7.94
   
   
   1. Μ = 11 and σ = 3: Incorrect
   2. Μ = 11 and σ = 7.94: Incorrect
   3. Μ = 77 and σ = 3: Incorrect
   4. Μ = 77 and σ = 7.94: Correct
